Jing Zhao commented on HADOOP-9763:
-----------------------------------
The patch looks very good to me. Only some minors:
1. TestLightWeightCache.java, it would be better if more javadoc/comments can
be added to TestLightWeightCache, such as the general steps for each check
process, and what is tested for each step.
2. Maybe we can assign an initial random value for
LightWeightCacheTestCase#currentTestTime?
